To obtain the best engine performance, it is essential not to
deviate from the mission profile for which it was produced
and set up. The engine must not be used for purposes other
than those stated by the manufacturer. IVECO MOTORS is
willing to examine any need for particular installations befo­rehand. Use of an electronically controlled injection system,
in providing the engine with performance benefits, requires
that the installer and maintenance specialist comply with
some fundamental rules, which will become more and more
commonplace as use of such equipment becomes progressi­vely more widespread. Boat outfitters and maintenance spe­cialists are invited to closely follow the instructions contained
herein. No modifications to the engine, its accessories and
components, are allowed.

Failure to comply with the instructions that follow shall
void the warranty and relieve IVECO MOTORS of all
liabilities.

For personnel safety

Specialists and installers are cautioned to comply with
workplace safety rules and to adopt prescribed individual
protection devices when working.

o Drain the cooling, lubrication and fuel lines only after

the fluids have duly cooled. The pressurized cap of the
coolant line may be opened only after the engine has
duly cooled.

o Batteries contain a highly corrosive sulphuric acid solu-

tion: must never be upset and must be handled with
the utmost caution to prevent spillage. Ensure that the
battery compartment is adequately ventilated.

Handling

The engine must be handled by experienced personnel,
using the prescribed tool or a rocker arm that keeps the
lifting lines parallel and with adequate equipment in terms
of capacity and size. The two eyebolts provided for lifting the
engine alone must always be used simultaneously.

Installation

o Knife switches or battery breakers may be used on the

power supply line of the engine electronic unit, provided
they are not used to shut off the engine.

o Do not modify the wiring harnesses; their length may

not be modified: use only available extensions.

o Do not use electronic device wiring harnesses not com-

pliant with the IVECO MOTORS directive, in terms of
length, type of conductor, location, clamping, connection
of the shielding and ear th braids.

o To avoid any interference, the wiring harnesses of the

different on-board electronic devices must follow diffe­rent paths from those of the engine electronic systems.

o Do not connect any extraneous user device to the engi-

ne electrical equipment.

o Do not energize the on-board electrical system of the

boat without first verifying that there are no short cir­cuits.

o Do not branch pipes off to draw fuel from the engine

supply lines.

o Do not make any change to the engine’s hydraulic circui-

ts and components.

o Do not execute arc welding operations before removing

the electronic units from their seating, placing them at an
adequate safety distance.

o Do not subject electronic units to temperatures excee-

ding 80°C.

o Do not paint electrical components and their connec-

tions.

o Do not alter the data contained in the engine control

electronic unit.

o Comply with prescribed procedures and torque values

when tightening threaded elements.

Start-up

o Ready the engine following the procedure set out in

Chapter 14.

o When starting the engine the first time, have suitable

means available to cut off air intake in case of a runaway
condition.

o Start the engine after ensuring that it is complete with

every part specified by the manufacturer and required
by the installation, without attempting to star t it with
caps and occlusions to the lubrication, cooling and fuel
feed lines.

o Check that the fluid lines are perfectly sealed, especially

lines for fuels and lubricants, which may cause fires and
consequent harm to persons and equipment.

o Make sure that the various pipelines are not in contact

with warm surfaces or moving parts.

o The installing yard is required to carry out tests to

verify the functional compatibility between the electri­cal-electronic equipment of the engine and the other
electronic equipment present on the boat.

Tests and tuning up

o Never disconnect the batteries when the engine is run-

ning.

o Remove the electrical connections from the batteries

before any operation on the electrical system.

o Ensure that the battery terminals comply with the exact

polarity, are properly tightened and protected against
accidental short circuits and corrosion phenomena.

4. GENERAL INSTALLATION CRITERIA

Accessibility

The engine must be located in such a way as to allow filling
and draining engine liquids when doing servicing operations.
Moreover, the relay box and the diagnostic push-button
present on it must be accessible, also when underway.

Anchoring

If anchoring is accomplished by interposing shock mounts,
they must be able to support the engine’s mass and the lon­gitudinal thrust exerted by the propeller shaft in motion.
If rigid mounting is adopted, particular care must be given to
support alignment and co-planarity.
Information on dimensions and fastening values are provided
in the “Installation Diagram”.

Combustion and ventilation air

Compliance with prescriptions on the quantity of air
required for combustion and ventilation assures a regular
operation of the engine even in adverse conditions and it
enables to deliver its maximum rated power (1).

Sea water line

It must be provided with an intake capable of preventing
the entr y of foreign bodies into the suction pipes. Between
the intake and the pump, it is best to interpose a gate to be
closed in emergencies or for extended idle periods and a
filter to stop the smaller impurities; it is also recommended
to install a suitably dimensioned and easily replaced zinc
anode.
The engine sea water line was provided by the manufacturer
with protection anodes to be replaced periodically.
The rubber hoses positioned along the pipeline shall be suffi­ciently rigid not to create choked areas caused by crushing (1).

Engine pre-heating

If the engine usage profile requires immediate delivery of
power at the highest rpm’s, it is recommended to install an
auxiliary pre-heater on the closed cooling loop.

Exhaust gas outlet

The exhaust gas outlet conduits shall be compliant with the
guidelines contained in the IVECO MOTORS publication
“Guide to the installation of marine engines”; it also provides
indications to compute the dimensions of the exhaust pipe­lines, which is the Yard’s responsibility.

Electric - electronic equipment

Provide a suitable arrangement of the relay box, and of the
optional electronic unit referring to the dimensions and posi­tion of the wire harnesses and the relative connectors.
Both units must be anchored in such a way as to dampen the
vibrations and stresses undergone by the hull while under­way and/or induced by the engine’s operation.

NOTE: Information about optional equipment are described
in the Chapter 21.

(1) The EDC engine electronic control is programmed to

reduce maximum deliverable power if the operating
parameters measured by the sensors show that criti­cal conditions have been reached, and if exceeded the
engine could be damaged.

7. FUEL LINE

Figure 7

For the installation, the following connections are required:

- from the tank to the prefilter

- from the prefilter to fitting to engine inlet

- from engine outlet fitting to the tank recirculation

Prefilter

The prefilter with priming pump, supplied separately from
the engine, must be fastened near the tank, in a relatively low
point of the line to allow for easy replacement the filtering
cartridge and/or the operation of the hand pump. Avoid the
use of additional mesh or paper filters along the feed lines
between prefilter and engine. To avoid introducing impuri­ties in the feeding lines inside the engine, do not place filter
cartridges pre-filled with fuel in the system.

Materials Characteristics

The fuel tank and the suction and return assembly must
withstand the continuous abrasion caused by a flow of fuel
oil of 250 l/h at a temperature of 90°C without noticeable
deformation or wear or release of material. Use of metal
tanks, preferably made of iron alloys, is allowed, provided

they are connected to the negative terminal of the battery
to prevent the accumulation of electrostatic charges.
Tanks must be provided with vents to avoid exceeding an
internal pressure of ± 5kPa (± 0.5 m of H2O column); their
shape and the suction assembly must be such as to assure a
suction at the maximum longitudinal and transverse inclina­tion allowed for the boat, with a residual quantity of fuel oil
considered “reserve”.
The suction inlet should be positioned in such a way as to
avoid taking in sludge. The return flow must be in such a way
as to facilitate the mixing of the returning fuel with the fuel
in the tank. If the tank is lower than the filter, then the return
pipe must always be submerged. The pipes and union fittings
of the fuel line must withstand a fuel oil flow rate of 250
l/h at a temperature of 90°C and a pressure of 3 bar (300
kPa) without noticeable deformation, wear or release of
material. Metal tubes, preferably made of iron alloys, are rec­ommended, taking care to connect each individual segment
to engine ground to avoid the accumulation of electrostatic
charges and inserting a vibration damper elastic joint on each
segment. The pipes used must be cer tified according to the
relevant Countries’ rules or to the standards issued by clas­sification Bodies.

Figure 10

The electrical equipment of the engine comprises a series of
components provided separately from the engine to enable
an easy and diversified installation, according to the Yard’s
design choices. The need to make accessible, at sea or under­way, the controls to the electrical components and to the
connector for diagnostics contained in the relay box may be
met through different installation arrangements.
Along with the coupling of all connectors provided in the
wire harnesses, completing the installation also requires the

connecting wire harness (12) for the sensor to detect the
presence of water in fuel (5), to complete the power line and
to connect the accumulator to the engine wire harness.
The connection of the J3 connector enables the electric
connection of the control module to the lubricating oil
pouring pump.
The JC connector is set for the connection to the emergency
stop button.

Power supply line

The power network must be carried out in order to avoid
using both the structure of engine and the structure of the
hull (if this is metallic). For this purpose the electrical star ter
motor and the alternator required for this equipment are
characterized by the presence of the terminals for electrical
connections both with the positive and with the negative
pole of the battery.

1. Alternator - 2. Electrical star ter motor - 3. Battery -

4. Engine wire harness.

The power supply line, to be built by the yard, comprises:

o A. Connection between the negative pole of the battery

and the terminal “–B” of the electric star ter motor
realized with a conductor having a cross section of at
least 95 mm2;

o B. Connection between the positive pole of the batte-

ry and the terminal “30” of the electrical star ter motor
realized with a conductor having a cross section of at
least 50 mm2;

o C. Connection between the “30” terminal of the alter-

nator to the positive “+B” terminal of the electric starter
motor, to close the power supply and recharge circuit
of the battery realized with a conductor having a cross
section of at least 50 mm2.

o D. Connection between the “−B” terminal of the alter-

nator to the positive “−B” terminal of the electric starter
motor, to close the power supply and recharge circuit
of the battery realized with a conductor having a cross
section of at least 50 mm2.

The connection of the electric equipment of the engine to
the battery has to be carried out via the two eyed terminals,
“+B” and “–B”, present on the wiring harness.

Battery recharging

This is accomplished through the power supply line of
the electric starter motor and connection to the +B of
the alternator. The electronic regulator of the alternator
that equips the engine allows an effective control over the
battery recharging operation.
If, due to installation requirements, the batteries need to be
positioned at a distance from the engine, we recommend
increasing the cross section of the power line conductors
and verifying recharging effectiveness by measuring voltage
across the batter y poles.

For the best control of the battery recharge cabling the line
relating to the S terminal of the alternator directly to the
positive pole terminal of the battery (see figure 17).

Supplementary services battery

To assure that the engine can be started with a sufficient
quantity of energy, it is advisable to provide for the instal­lation of a supplementary battery, dedicated to supplying
power to the on-board electrical services. The power line to
recharge it may be constructed according to the indications
provided in Chapter 20.

If one engine is installed

The battery used for services may be recharged interposing
on the power supply line a relay actuated by the recharge
signal of the alternator’s electronic regulator (L).

If two engines are installed

The presence of two generators allows keeping the recharg­ing functions separated: the generator (G1) recharges the
battery (AC1) dedicated to star ting both engines and pow­ering both electrical/electronic control circuits, whilst the
generator (G2) recharges the battery (AC2) used to power
the services.

In two-engine applications, it is essential to connect the
engine grounds to a common potential; the solution pro­posed in Chapter 20 fully complies with this need, assuring
the full functionality and independence of the two circuits.

1. Control selector from bridge or engine room - 2. Power
supply switch of the engine electric circuits - 3. Start button

alarm” 5. Button for managing acceleration and deceleration

- 6. Connector for diagnostic instrument -

7. Blink code emission LED (EDC) - 8. Signalling LED of

maintenance interval expiration - 9. Signalling LED for fault

engine operating parameters (WARNING).

This shall be installed and anchored in such a way as to
dampen the vibrations and stresses occurring when under­way, and they shall be accessible during ser vicing operations
and when underway. The electrical commands positioned
on the panel allow controlling engine star ting and stopping
directly from the engine room, while excluding any possibil­ity that anyone may involuntarily star t the engine from the
bridge, during ser vicing operations.
On the relay box is located the multipolar connector (6),
protected by a screw-on lid, for connection with the com­puterized diagnostic tools prescribed by IVECO MOTORS.
Inside the box, anchored to a printed circuit board, are pres­ent the power management relays of some components and
the elements that protect the electrical lines against short
circuits or excessive current absorption. These components
perform a similar function to that of fuses, almost totally
avoiding the need to restore the electrical continuity of cir­cuits subjected to an anomaly condition. These components
are able to limit and eliminate short circuit currents without
melting, restoring their own and the circuit’s electrical conti­nuity, once the cause of the anomaly is removed.

10. High coolant temperature (SATA) - 11. Low oil pressure

(SBPO) - 12. Pre/post heating (SCP) - 13. EDC Malfunction (EDC).

The Indications and Alarm Module comprises the indicator
lights and the electronic alarm interface, timing and stor­age circuit. It is programmed in such a way that when it is
powered, all indicator lights are lighted, with the exception
of those for “pre-lubrication”, “pre-post heating” and “EDC”
failure and a sound signal is emitted by the buzzer.
The buzzer may be silenced before the end of the test, acting
on the appropriate control.
During the star ting phase and for the subsequent 15 sec­onds, needed to stabilize the low oil pressure signal, all the
module’s functions are inhibited; once this time interval has
elapsed, every alarm state detected by the sensors will cause
the associated indicator to be lighted and the buzzer to be
powered; the exceptions are the “pre-lubrication” and “pre­post heating” indicators, given only visually.
When a new alarm state is detected, the indicator light will
flash to highlight the occurrence with respect to any others
which may be ongoing at the time. When the sound alarm is
shut off, the light indicator will remain lighted and the alarm
will be stored until the engine is stopped.

The standard set-up of the V08 ENT M75, V08 ENT M11
and V08 ENT M12 provides for use of the indicators: SBLA,
SIFA, SIFC, SIFO, EDC, SS.

Installation

In order to drill holes on the area where the panel is to be
mounted, refer to the dimensions indicated in Chapter 11.

Operation of the panel

After completing the electrical connections and engine
preparation, perform the tests required for the first star t, as
described in Chapter 18.
Verify the proper operation of the panel, proceeding as fol­lows:

o Make sure that the “ENGINE ROOM / BRIDGE” switch

of the Relay Box is in the “BRIDGE” position, then
turn the key switch to the first position and verify that
the instruments are powered and the Indications and
Alarms Module runs the alarm test for about 5 seconds
according to the procedures set out below.

o Once the test is complete, only the indications prescribed

for the engine not running must remain lighted: e.g.
“alternator charge” and “low oil pressure”; the analog
instruments must provide values consistent with the
relevant physical parameters.

Testing the engine start function

Turn the key switch in the second position and release it
quickly; the start function is fully controlled by the ECU and
begins when the key is released.

Checking indications

After starting the engine, verify whether the operating
modes of the Indications and Alarms Module are similar to
those set out below.
Using appropriate measuring instruments, verify the consis­tency of the indications provided by the analog instruments.
Verify the indication of the panel revolution counter, compar­ing it with the one measured by a reference instrument; if the
indication is different, proceed as described below.

Testing the engine stop function

The engine is stopped and the panel is disabled by returning
the key switch to the resting or zero position.
The panel has an engine stop push-button whose function is
only enabled in versions where the engine stops as a result
of the excitation of an actuator, i.e. engine versions requiring
certification by Certification Bodies.

14. PREPARING THE ENGINE FOR FIRST START-UP

15. TESTS BEFORE THE FIRST START-UP

1. Drain the residual 30/M protective oil from the sump.

2. Pour into the lubricating loop only lubricating oil of the
type and in the quantities set out in the Refilling Table.

3. Drain the CFB protective liquid from the fuel loop,
completing the operations as indicated under item 3. of
Chapter 19.

4. Remove the caps and/or seals from the engine intake,
exhaust, aeration and venting ports, restoring normal
conditions of use. Connect the inlet of the turbocharger
to the air filter.

5. Connect the fuel loops to the boat tank, completing
the operations set out in item 4. of Chapter 19. During
filling operations, connect the pipe returning fuel to the
tank to a collecting container, to prevent residues of CFB
protective liquid from ending up into the boat tank.

6. Verify and refill engine coolant as prescribed.

7. Remove from the engine the labels with the inscription
“ENGINE WITHOUT OIL”.

Although they are extremely important, “common sense”
checks such as the exposure of sensitive parts (plastics, wire

harness, electronic units, etc. ...) to heat, and those that for

years have characterized the quality of the work performed
in the yard, are not mentioned herein.
Tests of the proper operation of the engine and the com­ponents of the electronic control system may be performed
rapidly and with the utmost reliability using specific diagnostic
tools, available from IVECO MOTORS Technical Assistance
Centres.

Fuel tank suction

Verify the fuel suction at the maximum allowed longitudinal
and transverse inclination, with the residual quantity of fuel
considered “RESERVE”, such as to cause the reserve indica­tor light to be permanently lighted.

Throttle lever position sensor

In the positions of minimum and maximum travel, verify the
correlation between the position of the throttle control
valve on the bridge and the position of the sensor rod.

Instruments and control panel

Verify the efficiency of all light indicators, as described in the
related Chapters.

16. FIRST ENGINE START

Before starting the engine, please make sure the sea water
gate valve is open, check the levels of the lubricating oil and
of the engine coolant, and complete venting the air from the
fuel feed loop, acting on the hand pump of the prefilter or
with the aid of a dedicated electrical pump. Loosen the vent
fitting on the prefilter and operate the pump until only fuel
without air flows out.

Venting fuel supply line

1. Prefilter vent fitting - 2. Vent fitting on the filter support -

3. Vent fitting on the high pressure pump.

o Loose the vent fitting on the prefilter (1) and operate

the pump until only fuel without air flows out. Tighten
the vent fitting.

o Loosen the vent fitting (2) on the filter support and

operate the pump until only fuel without air flows out.

o Tighten the vent fitting (2) and continue pumping during

the initial star t-up phases.

Make sure that the fuel that flows out of the fitting is not
dispersed in the environment.

Only if the engine starting is very difficult, stop the engine,
insert a hose on the vent fitting of the high pressure pump
(3), loose the junction and start the engine for a few seconds.
Stop the engine, remove the hose and tight the junction to
the prescribed torque value. Make sure that the fuel that
flows out of the fitting is not dispersed in the environment.
Start the engine.

CAUTION

Never attempt to vent the high pressure system as this is
useless and extremely dangerous.

CAUTION

Avoid accurately that fuel comes into contact with the
alternator belt.

Start-up procedures

1. Control selector from bridge or engine room -

2. Power supply switch of the engine electric circuits -

3. Start button from engine room -

4. Button for managing acceleration and deceleration.

The electrical equipment of this engine allows starting it
from the “engine room” and from the “bridge”.

NOTE

A few moments after start-up, make sure sea water is cor­rectly drained from the relevant circuit.

Starting the engine from the bridge

This is allowed only if the Relay box switch (1) is in the
“BRIDGE” position.
Procedures and warnings are provided in the operation and
maintenance manual.

Starting engine from the “bridge”

- Switch over the switch (1) of the relay box in the posi­tion “ENGINE ROOM”.

This operation excludes all the bridge controls and must be
absolutely avoided when the engine has been started.

- Switch over the switch IGNITION (2) to power the
electric circuits of the system and enable the controls
available on the panel.

- Press the button START (3) to start the engine.

WARNING

The engine start is fully controlled by the ECU; the start-up
phase begins when the button START is released.

Engine shut-off from “bridge”

The engine shut-off occurs switching over the switch IGNI­TION (2).
Bringing again the switch (1) in position “BRIDGE”, the use of
the controls will be disabled on the Box, enabling the start­up only the bridge controls.

RPM control

To allow easily to control engine RPM from the “engine
room”, a simultaneous acceleration/deceleration function
(RPM+/RPM-), active only when the switch (1) is in the
“ENGINE ROOM” position, and the switch (2) is in IGNI­TION position.

Acceleration (RPM +)

If, the engine is running, and RPM+ / RPM- push-button (4)
is held down in the “RPM+ position, then engine rpm are
progressively increased. The increase ends when the push­button is released, allowing the engine to run at the desired
rpm.

Deceleration (RPM −)

If the engine is running, and RPM+ / RPM- push-button is
held down in the “RPM-” position, a progressive reduction in
rpm is obtained. The reduction ends when the push-button is
released, allowing the engine to run at the desired rpm.
The set out engine speed will be kept until the next engine
shut-off.
The engine shut-off resets every previous configuration.

NOTE
The effect of the RPM + e RPM – controls varies according
to the duration of the operation:
it is achieved a very slow variation during the first 3 seconds;
continuing the operation, the regulation becomes much
more effective and enables to complete the full range of the
engine speed in a overall time of about 20 seconds.

CAUTION

Never operate the “BRIDGE - ENGINE ROOM” switch
when the engine is running.

Once the first star t-up phase is complete, verify that:
o There are no liquid leaks from the coolant loop pipeline

junction hoses.

o There are no exhaust gas leaks in the hull.

o In order to carry out the cooling system degassing, do as

follows:

1. Venting screw.

Stop the engine, then loose the venting screw (1) carefully to
degas the expansion tank. When the operation is completed,
tighten the screw to the prescribed torque, start the engine
and keep it up for a few minutes. Stop the engine and verify
the coolant level again, fill it up, if necessary.
Make sure that the coolant that flows out is not dispersed in
the environment.

o Complete the instrument panel operation tests as

described in the related Chapters.

o Verify that the power supply voltage across the batter y,

after about 15 minutes with the engine running, is no
less than about 26 V.

o Stop the engine and delete any “errors” which may have

been stored in the injection system ECU during the sta­bilization phases. The error deletion can be carried out
by the diagnostic instrument IVECO SERVICE TOOL.

17. EDC ECU INDICATION LIGHTS

CHECK Indication light

4. Reset button of the “maintenance alarm” -

7. Blink code emission LED (EDC) - 8. Signalling LED

of maintenance inter val expiration - 9. Signalling LED for fault

engine operating parameters (WARNING).

The ECU continuously monitors its own operating conditions,
as well as of the engine and of components connected to it
with complex auto-diagnosis routines.
The identification of anomalies causes:

- the anomaly data storage in the ECU.

- the blinking lighting of the fault indication light EDC on
the instrument panel.

- the lighting of the green indication light CHECK (7) on
the relay box.

The blinking lighting of the EDC fault indication light has
the purpose to inform about a detected anomaly, whose

identification is taken “reading” the blink code of the CHECK
indication light.
(Indications for decoding codes are in the following
chapter).
The code emission happens automatically and sequentially
when the anomalies are detected; the sum of the current
anomaly code is designated “list”.

Each single code is organized in 3-digit numerical blocks with
a fixed lighting duration equal to 0.6 s.

The pauses (switch-off time) have a different duration to
distinguish the given type of information:
pause between blinking of the same digit 0.36 s
pause between different digits of the same code 1.5 s
pause between different codes of the same list 3 s
pause between consecutive lists 6 s

The emission is continuative, i.e. the code list is repeated
consecutively with the same order; a 6-second pause
separates the list repetitions.

NOTE
Only the codes of the current anomalies are returned; a
temporary anomaly causes the emission of the associated
code for the whole period the anomaly is present. The
emission code stops when the operating conditions are
restored, while the data concerning the anomaly are stored
in the failure memory of the ECU.

The stored information are able to be decoded and erasable
by the IVECO SERVICE TOOL.

WARNING Indication light

The ECU carries out a control activity on the operating
conditions through the analysis of the detected operating
parameters; it evaluates the behaviour of the single signals
emitted by the sensors and classifies the situation, according
to predetermined threshold, activating the red indication
light (9 figure 45).

Blinking indication light - warning level:

Lighting cycle of 0.6 s and pause of 0.24 s.
It indicates that the value is slightly above the normal
threshold; the user of the vessel does not notice any
difference in the engine behaviour.

Indication light constantly On - derating level:

It indicates that the value is significantly above the normal
threshold; the maximum power of the engine is reduced to
protect its intactness. The user of the vessel can notice the
reduction of the power of the engine.
NOTES
Only the current anomalies enable the behaviour specified
above; a temporar y anomaly causes the lighting of the
indication light, according to the modalities illustrated, for
the whole period the anomaly is present. The emission code
stops when the operating conditions are restored, while
the data concerning the anomaly are stored in the failure
memory of the ECU.
The signalling is available on the relay box only, and does not
involve any other indications on the instrument panel.

The stored information are able to be decoded and erasable
by the IVECO SERVICE TOOL.

SHUTDOWN (preliminary)

When the most critical thresholds exceed their normal
values, it can be enabled the forced engine shutdown.
The next time the engine is star ted, if the normal operation
are restored, there will not be any lighting signalling, while
the data concerning the anomaly are stored in the failure
memory of the ECU.

Parameter list that can cause warning, derating or shutdown
conditions:

Engine coolant high temperature
Intake air high temperature
Engine oil low pressure
Engine overspeed
Fuel high temperature
Engine oil low temperature
Engine oil high temperature
Rail low pressure
Rail high pressure
Loss on the high pressure fuel line
Intake air high pressure
Intake air low pressure
Power supply voltage

Signalling maintenance interval expiration

The lighting of the indication lights MAINTENANCE (8
figure 45), caused by the ECU, indicates the need to perform
the periodical lubricating oil replacement.
When the operation is performed, it is necessary to press
the button (4 figure 45) to restore the counter and begin a
new operating cycle. The signalling is available on the relay
box only, and does not involve any other signalling on the
instrument panel.

18. UNDERWAY CHECKS

ECU Temperature

Verify that the temperature of the surface of the electronic
engine control unit, after 30 minutes underway at full engine
power, is less than +70°C.

Engine compartment vacuum

Verify that value of ambient air pressure in the engine room
with the engine(s) at full load and maximum power output
complies with the value specified herein.

Combustion air temperature

Verify that the temperature in the engine room, after 30
minutes underway at full engine power, does not exceed
45°C (V08 ENT M75) or 50°C (V08 ENT M11 e V08 ENT
M12) and, in any case, does not exceed the value of external
temperature by more than 15°C.

Exhaust back-pressure

Verify that the value of back-pressure present at the inlet of
the exhaust gas conduit, with the engine(s) at full load and
maximum power output, complies with the value specified
herein.

Exhaust temperature

Verify that the temperature of the exhaust gases under
maximum engine power output conditions is close to the
prescribed value; to determine the propeller power absorp­tion curve, it will also be possible to obtain from the ECU
parameters the fuel injection values by using the IVECO
MOTORS tool.

Fuel temperature

Verify that the temperature of the fuel in the low pressure
line, while underway at full power and with a stable quantity
of fuel in reser ve, does not exceed 70°C. A higher value
would entail a reduction in engine performance. If the ten­dency to reach the maximum allowed temperature is noted,
install a heat exchanger for the fuel.

Pressure in the fuel supply line

To assure the regular operation of the engine and the reli­ability of the components of the fuel supply and injection
system, you need to verify that:

o vacuum in the fuel oil supply line to the low pressure

pump is less than 0.5 bar relative (5000 mmH2O);
pressure in the fuel oil supply line to the low pressure

pump is less than 0.5 bar relative (5000 mmH2O);

o pressure in the fuel oil return line to the tank is less than

0.2 bar relative (2000 mmH2O).

Measures are carried out inserting a “T” junction near the
fuel inlet and outlet, taking care to avoid any air suction. Val­ues are read at variable rpm, from idle to maximum, at 200
rpm inter vals.

If there are any symptoms indicating the possible presence of
air in the fuel supply line, a check may be made by inserting
a clear tube, arranged as an inverted U, before the engine
inlet junction.

19. PREPARING THE ENGINE FOR LONG IDLE PERIODS

To prevent oxidation to the internal par ts of the engine and
to some components of the injection system, if idle periods
exceeding two months are expected, the engine needs to
be prepared with six-month periodicity, proceeding as
follows:

1. Drain the lubricating oil from the sump, after heating the
engine.

2. Pour 30/M protective oil (alternatively, oil conforming to
MIL 2160B Type 2 specifications) into the engine to the
“minimum” level marked on the dipstick.

Start the engine and let it run for about 5 minutes.

3. Drain the fuel from the injection line and from the filters,
taking care to prevent the fuel from coming in contact
with the alternator’s belt.

4. Connect the fuel line to a tank containing CFB protec

­tive liquid (ISO 4113) and assist the inflow of the liquid
by pressurizing the line and turning the engine over for
about 2 minutes, after excluding the operation of the
injection system. The required operation may be carried
out by directly polarizing the terminal 50 of the electric
starter motor with positive voltage 24 V, using a conduc­tor prepared for the occasion.

5. Nebulize 30/M protective oil at the rate of about 100 g
(10 g per litre of displacement) in both turbochargers,
while the engine is turning over as described above.

6. Close with suitable stoppers or seal with adhesive tape
all engine intake, exhaust, aeration and venting ports.

7. Drain the residual 30/M protective oil from the sump; it
may be re-used for 2 more engine preparation opera­tions.

8. Apply tags with the inscription “ENGINE WITHOUT
OIL” on the engine and onboard panel.

9. Drain the coolant, if it has not been mixed with anti­freeze and corrosion inhibiting agents, affixing tags to
indicate that the operation has been carried out.

If external parts of the engine are to be protected, spray
protective liquid OVER 19 AR onto unpainted metal par ts,
such as flywheel, pulleys and others; avoid spraying belts, con­nector cables and electrical equipment.

1. Oil discharge control.

Lubricating oil exhaust operations are simplified by the
presence of an electrical control system connected to the JG
connector of the interface wiring harness. Manual control for
exhaust operations is positioned on the front panel unit. For
safety reasons, control is enabled only with the key switch in
the “OFF” position.

1. Not used - 2. Not used.

The module (on request) is connected to the JG1 connector
of the interface wiring harness.
The task of pre-lubricating the engine’s internal components
is managed and controlled by the electronic circuit of the
module when the key switch is placed in “ON” position.
